2.2 System bus
2.2.1 RS 485 bus termination
If the reader module is the last one on the bus, it is advisable to terminate the RS 485 system bus so that there is no
reflection on the line. Use the termination resistor 150Ω which is a part of the packaging.
2.2.2 RS 485 idle states
This reader module does not allow to set the idle states of the system bus. Set the idle states on converters APSLAN,
CON 110.IP or REP 485 if needed.
2.3 Assembly
2.3.1 Radio signal interferences
If a 125 kHz reader is used, it is necessary to take into account another 125 kHz reader in direct range - for example when
checking the door on both sides. In this case, the readers may interfere with each other. In the techfass system, it is
possible to use the so-called synchronization of reading between the reader and the reading module, which then do not
interfere with each other.
In general, if possible, we avoid mounting on metal substrates, it is recommended to perform a practical reading test or
contact [e-mail].
Interference along the line, e.g. from an interfering power supply, can affect the reading distance or the reader's own
communication.

4 Wiring diagram
4.1 Connection possibilities MREM 81 MTM(VR)
Reader module can be connected as follows:
▪USECASE A: Reader module configuration and settings.
If we want to set the reader module and its parameter values, eg what frequency it should read, what HW
address it should have, whether the lock is reverse or standard, etc., it must be connected to the converter, eg
APSUSB or APSLAN and use the desktop application APS Reader, or to CON 110.IP and use the WebHit
application website.
▪USECASE B: System-wise, where the individual reader modules are connected to the RS485 bus, where up to
In this case, the reader module is independent on the entry panel, it can operate autonomously or as part of the
APS mini Plus system. The actual configuration of the module and its settings can be performed using the
APSUSB converter and the APS Reader program.

www.techfass.com RFID reader module MREM 81 MTM(VR)
▪USECASE C: As a part of a modular MTM entry panel. “Easy family house”installation type.
The control output for the lock of the reader module OUT1 is connected to the input for the exit button of the entry panel
MTM. The lock itself therefore is switched by MTMV / 01 or MTMA / 01. The function and connection of the intercom itself
is independent of the reader module connection, only the inputs and outputs are shared. The door contact is connected
to the reader module at input IN1. This topology has higher demands on the system backup, as the backup batteries
must keep not only the reader module but also the intercom entry panel running. If we want to regularly administer or
configure the system centrally (more reader modules or door controllers are connected in the system), we will connect
the RS485 system bus. Its end is fed into the switchboard and connected to the LAN or the Internet using the APSLAN
converter or the CON 110.IP cloud connector.
▪USECASE D: As part of a modular MTM entry panel, easy installation example, simply connect the 4 wires of
the reader module.
In this case, the reader module is a part of the entry panel and the lock is controlled via the OUT 1 output of the reader
module. The control from the entry panel (opening by the receiver) takes place in such a way that the lock output of the
panel is connected to the IN2 input of the reader module in parallel with the exit button. In this connection, the door is fully
under the control of the reader module, and it is therefore possible to back up only the reader module and not the intercom.

www.techfass.com RFID reader module MREM 81 MTM(VR)
For reverse lock mode, just switch the settings in the control software. It is necessary to connect the output GND of DC
sources VAS / 101 and 12 / 24 Vdc.

6Operating modes
There are two basic operating modes for the MREM 81 reader module.
▪Standard operating mode
▪External reader with wiegand output
6.1 Standard operating mode
Main operating mode. In this mode, the module acts as a controller for one door, reads RFID media and determines in its
memory whether or not the user should be authorized to enter and controls the lock output.
The module can be in online or offline standard operating mode. The function is identical in both modes, with the difference
that in the online mode, the module statuses are reported via the communication line (after changing the mode from offline
to online, the event archive is read from the module's memory). In both operating modes, the module can switch to
programming mode (after reading the programming card).
6.1.1 Offline mode
Offline, or autonomous / standalone mode. One module alone or more modules on the RS 485 bus, but without
connection to a PC. In this mode, events are stored in the module's internal memory, module authorizes users according
to the stored set access rights. Settings / configuration are performed by default using a PC or programming cards.
6.1.2 Online mode
In Online mode, the module or more modules on the line are connected to a PC running the relevant application such as
APS Hit or APS Administrator or the line is connected to the cloud using CON 110.IP and the administrator works in the
WebHit web application. In this case, each event is immediately written to the application.
6.1.3 Online authorization
The APS mini Plus system implements the option of Online authorization of access authorization. In such a use, the
connected PC decides on the validity of the read ID authorization. The reader must be MLO licensed to use it in this
authorization mode.
! Note: This feature is currently only available on desktop applications.
6.1.4 Secure lock control with WIO 22 module
The MREM 81 module itself contains a switching open drain transistor and there are connected wires to control the lock.
In this simple configuration, it is advisable to install the module in a safe zone, where we do not expect an attempt to
overcome so that someone will want to get to the cabling to control the lock. If we need the module to switch ‘‘ safely ‘‘,
we connect the WIO 22 module to its Wiegand output, we place WIO in a safe place, eg in a rack / cabinet or from the
inside above the door, from where it already controls the lock. The WIO module must first be paired with the MREM 81
reader module.

7Function
7.1 Functions of the reader module
▪Standard "Door open" function
▪Lock control
▪Door status monitoring
▪Exit button status monitoring
▪Activation of the alarm output / buzzer signaling when an alarm condition is indicated
The "Door open" function can be activated in three different ways
▪By reading a valid ID (card, key fob,…)
▪By pressing the exit button (depending on the configuration) - cannot be used during the alarm
▪Software, via communication line
7.2 Function ‘‘Door open‘‘
In the case of the standard lock control mode, after activating the "Door open" function, the release of the lock relay and
the buzzer are activated (unless disabled by configuration). This state lasts until the door is opened, but no longer than
the time set by the "Lock activation time" parameter. Then the lock output is deactivated and the standard function is
terminated.
In the case of the toggle lock control mode, after activating the "Door open" function, the relay output toggles and the
buzzer is activated (if it is not disabled by the configuration). The acoustic signaling lasts as set. The relay output remains
unchanged until the next activation of the "Door open" function.
In the case of the pulse lock control mode, after activating the "Door open" function, the relay output is activated for the
time given by the parameter Pulse width (ms).
In the case of the standard lock control mode, reading a valid card during lock activation will cause a new lock timing.
Online authorization
If the reader module reads the ID card during the "Door open" function via the communication line (in online mode) and if
the read ID is not valid, it is signaled by an acoustic signal "invalid ID" regardless of the configuration of the acoustic lock
release message.
7.3 Permanent lock release based on valid time schedule
When this function is set, the lock is permanently released during the validity of the respective schedule, the reading of a
valid ID is reported via the communication line (in online mode). When the lock is permanently released, the alarm state
of the forced door does not occur.
The setting of the permanent release of the lock according to the time schedule and the toggle lock control mode are
mutually exclusive.
7.4 Function of ID with flag
It is possible to set a flag for each ID, which will cause an alarm ‘‘ Alarm - ID with the flag ‘‘ when reading the appropriate
ID (and will activate the alarm output for a defined time).

www.techfass.com RFID reader module MREM 81 MTM(VR)
7.5 ID expiration
It is possible to set a date for each ID at which the ID expires and will no longer be valid. The expiration is evaluated every
time the data in the RTC module changes and when new access rights are loaded.
! Note: This feature is currently only available on desktop applications.
7.6 Antipassback function (APB)
Antipassback can be implemented in two ways:
▪Time - the user must not use the ID medium repeatedly for a defined time
▪Zone - the user must not repeatedly enter the area in which he is present
The antipassback function is used only for users who have defined access according to a schedule. The function does
not apply to users with permanently valid access.
Zone and time antipassback IDs can be reset by re-inserting the IDs using the programming cards. After reloading the
access rights by the program, the antipassback flags are reset for all IDs.
The zone and time antipassback flag is written according to the configuration either immediately after reading the ID, or
only after opening the relevant door (opening the relevant door contact).
7.6.1 Time antipassback
The time antipassback is defined by setting the duration (in minutes), which is set for the given ID when passing at the
given address. The next time the ID is identified at the relevant module address during the timer run for the given ID, a
time APB alarm is triggered. The following parameters affect the time antipassback function:
▪Default value of the APB timer - the time for which the APB timer alarm is triggered at the next ID identification,
the timer is set for the given ID when passing at the given address.
▪Enable door opening after time APB alarm - if the function is enabled, the Door opening function is started in
case of time APB alarm.
7.6.2 Zone antipassback
Zone antipassback is defined by enabling / disabling this feature. The zone antipassback flag is set for the user after
passing. Upon further identification, a Zone antipassback alarm is triggered in the case of a flag set for the given ID. The
following parameters affect the zone antipassback function:
▪Enabled - global enable / disable of the zone APB flag setting function.
▪Enable offline mode - if not set, the module works in offline mode as if the zone antipassback function was not
implemented at all.
▪Enable door opening after APB alarm - if the function is enabled, the Door opening function is started in case of
a zone APB alarm.
7.7 Disabling the reader module
Disabling of the reader module function can be configured on the second input or on the third I / O port of the module.
The function activation logic on each port is configurable. The function is activated if at least one of the ports is active and
set as disable.
The module in the disabled state exhibits the following behavior:
▪Users with set time schedule cannot trigger the door open function if it is disabled
▪Disable does not apply to the users with permanently valid access (no time schedule)
▪The remote door opening function cannot be performed
▪Remote door opening with ID is blocked for users with time schedule.
Changes in the status of the disable function and the blocked action are recorded in the event archive.
This function is useful for example in combination with intruder alarm system.
7.8 Alerts and their signaling
The following alert conditions may occur during the reader module operation:
1) Tamper. (these in no tamper in the reader module MREM 81 NO/IGBKP)
2) Forced door.
3) Door ajar.
4) Antipassback alert (time, zone).

www.techfass.com RFID reader module MREM 81 MTM(VR)
5) Alarm ID with flag.
To deactivate any alert, please set its value to “0”.
Alerts are reported as follows:
▪In software, by system bus (alerts 1, 2, 3, 4, 5)
▪Acoustic (alerts 1, 2, 3, 4)
▪Activating the alert output (alerts 1, 2, 3, 5)
The alarm message via the communication line assumes an online connected PC with the appropriate software suitable
for online operation (APS Administrator).
The audible alert message is twofold:
▪Continuous tone (distortion)
▪Intermittent tone (knocked out and long open door, APB alarm)
The acoustic message ends either after the set time (see configuration table)
or after reading a valid ID on the relevant module.
When one of the relevant used alarm conditions occurs (signaling time
alarm must be greater than 0) the alarm output will be activated. On this output is
it is possible to connect the alarm device directly or to further process its signal.
The triggering of the alarm is controlled by a logical connection or between individual types
alarms.
The alarm condition is terminated by restoring all idle conditions (closing the door, fitting the cover, etc.).
7.8.1 Tamper
The MREM 81 NO/IGBKP reader module is not equipped with a Tamper sensor to detect that the lid is open.
7.8.2 Forced door
The "Forced door" status occurs when the IN1 input of the module is opened without first activating the "Door open"
function. The only exception is the exit button / handle contact signal activation from the inner side of the door.
7.8.3 Door ajar
The "Dopr ajar" status is activated by opening the door for a longer time than allowed (set), see the configuration table.
7.8.4 Antipassback alarm
Antipassback alarm is generated when a valid card is read at the time of blocking the user by Time APB,
or when the user is blocked by a Zone APB.
7.8.5 Alarm ID with flag
Alarm ID with a flag occurs when a card (ID) with flag is read.
7.8.6 Reading ID in time of alert
Reading a valid ID has no effect on the alarm conditions themselves. It is terminated with a valid ID
only an audible alarm, followed by the "door open" function. Reading an invalid ID only interrupts the audible alarm for the
duration of the "invalid ID" signaling.
